Description

A kind of preparation method of absorbent cotton
Technical field
The invention belongs to absorbent cotton production technical field, and in particular to a kind of preparation method of absorbent cotton.
Background technology
The main component of cotton fiber is alpha-cellulose, and typically by high, fiber length of maturity etc., matter is measured is referred to as cotton, The outside 40% or so taken from cotton boll belongs to cotton；And by maturity is lower, fiber is relatively short, quality relative mistake Some are referred to as cotton linter, i.e., residue 60% is cottonseed, one layer of short flannel cotton is enclose on cottonseed, cottonseed obtains cotton through mechanical stripping Flower seed and cotton of short staple, cotton of short staple account for 20% or so of cotton total amount.They are referred to as cotton fiber, and the former is used for textile industry, The latter is usually used in chemical industry.But cotton of short staple is that one kind contains more broken cotton seed hulls, broken cotton floral leaf, broken cotton peach shell, dust etc., no Industry and life can be directly used in.In addition to some impurity that external energy is seen, cotton linter often contains various accompanying impurities, and these are miscellaneous Matter belongs to the accompaniment of cellulose, is broadly divided into two major classes：One kind is polysaccharide and derivative, as pentosan, more contracting hexose, Pectic substance and starch etc.；Another kind of is non-glucide, as lignin, resin or grease, wax, protein, inorganic salts and A small amount of tannin, pigment etc., certain technical finesse means are had to pass through during use, can just be made after removing these accompanying impurities With material after treatment turns into a kind of new material in physics and chemical property all there occurs great changes, and we will It is referred to as absorbent cotton, is called purified cotton, cotton pulp pool etc..
The absorbent cotton absorbent time that traditional method is prepared is long and water absorption is few, has not met the demand of modern people, In addition biocompatibility is bad, can not especially meet the needs of medical procedure.
The content of the invention
A kind of preparation method for absorbent cotton that the present invention provides for above-mentioned weak point, the present invention is using cotton linter as original Material, is prepared into absorbent cotton, the preparation side by steps such as opener-removal of impurities-cotton carding-degreasing-bleaching-pickling-washing-dryings Method is simple, and cost is low, and the liquids quality such as water that the absorbent cotton prepared absorbs in a short time is more, has saved the time, meets The demand of contemporary people.
To achieve the above object, the technical solution adopted for the present invention to solve the technical problems is：
A kind of preparation method of absorbent cotton, comprises the following steps：
(1) opener：Fritter short flannel using opener by closely knit cotton linter shredding for nature diastole, in favor of follow-up Processing；
(2) clean：Larger impurity on cotton linter after opener is removed, then cleared up its solid particle polluter with recycling machine Totally, most its dust is removed totally through cyclone dust removal machine afterwards；
(3) cotton carding：Loose processing is carried out again to the cotton linter after removal of impurities, makes cotton piece thickness uniformity, every 1.5- 1.8kg, weight 15-18kg is often wrapped, must not exceed 18kg；
(4) degreasing：Cotton linter after cotton carding is placed in bucking kier, every pot of 850-1200kg, it is 22- then to add concentration 28g/L temperature is 70 DEG C of NaOH solution 8m3, make alkali lye infiltrate through cotton carding after cotton linter in, then heat to more than 95 DEG C Start convection current, calculated from being started convection current, kiering 7-8h, it is 95-100 DEG C that kiering temperature is kept in scouring process, and kiering terminates Afterwards by recycle of alkali liquor, hot water injection, cold water flush, drain；
(5) bleach：The cotton linter of degreasing is taken the dish out of the pot, is closely placed in Bellmer, concentration 2.0-2.8g/L Calcium hypochlorite solution 8m3Material after degreasing to be bleached, the whitening cycle time is 4-5h, then reclaims bleaching liquid, Clear water rinses, and drains；
(6) pickling：By 95% H2SO4It is diluted with water as 4-7g/L acid solutions, acid solution is filled into pond, the cotton after immersion bleaching Short flannel, circulation time 2h, clear water rinse；
(7) wash：Cotton linter after pickling is cleaned with water, it is 7.0-7.5 to be washed till solution ph, is then dehydrated；
(8) dry：It will be dried after material exhibition cotton after washing dehydration, examine, packaging, obtain absorbent cotton.
Further, every 10min convection current 1-2 times in step (4) scouring process.
A kind of preparation method of absorbent cotton provided by the invention, has the advantages that：
(1) present invention passes through opener-removal of impurities-cotton carding-degreasing-bleaching-pickling-washing-drying etc. using cotton linter as raw material Step is prepared into absorbent cotton, and the preparation method is simple, and cost is low, and the alkali lye, bleaching liquid, acid solution, water in preparation process are all The dosage of alkali lye, bleaching liquid, acid solution, water can be reduced with recycling, while decrease the pollution to environment.
(2) the absorbent cotton quality prepared of the present invention is good, can meet pharmaceutical requirements, good biocompatibility, in a short time It can absorb more liquid, efficiency high.
(3) every 10min convection current 1-2 times, this operation alkali lye can be made to permeate uniformly, completely in scouring process in skimming processes Into cotton linter so that the various accompanying impurities in cotton linter remove well.
